I seen Java ?

Jan 28
I was going to download Air and I seen Java - Is Adobe Air, Flash Player and Shockwave void of the Java Virus and Java Infection ? But is Java script the Java with the Problem or Java scipt prograimmg ? I wonder because I had problems downloading Abode products - it kept stalling displaying "timed out".
Thanks,
Darren D.

Adobe does not use Oracle's Java. AIR and Flash use their own virtual machine. Your download issues are another matter, but you did not provide any detailed information, so I'm afraid this si not going anywhere. Simply try anotehr browser and use this:

I have some general questions about Java

Is there a such thing as a list of every Exception in Java?
Is there somewhere I can look at examples of try statements, catch statements I guess tutorials on the basics of Java, like what would constitute these statements.

Thanks so much. This helps with the questions that I have. I am taking a class, where the only input I'm getting is "feedback". I'm expected to read the chapter, do the assignments, mind you this is the first time I have ever seen Java. Most of the class dropped out and now I see why.
I asked the questions I did, because I didn't know "what" I understood the books explanation of the try statement pertaining to it's example, but I have nothing to apply "across the board" when it comes to try statements. The links you gave me were great, I now know how to tailor my questions. I will use the example in the link you gave me and try to equate it to my assignment. (This is a perfect example!)
readFile {
    try {
        open the file;
        determine its size;
        allocate that much memory;
        read the file into memory;
        close the file;
    } catch (fileOpenFailed) {
       doSomething;
    } catch (sizeDeterminationFailed) {
        doSomething;
    } catch (memoryAllocationFailed) {
        doSomething;
    } catch (readFailed) {
        doSomething;
    } catch (fileCloseFailed) {
        doSomething;
}I know that hitting enter more than once, entering a non integer (7.4), or entering a character "w" will cause a NumberFormatException. I am to enclose the methods in the try statement. Does that mean that I start with try {, then the section of code? Then I need a statement or code? This is where I am confused. I look at the example above and those are actual statements. Will it come a time when after "try" i will need code?
What would be my statement? Is this something that I make up? ( I know these questions are dumming it down ALOT but once I get why something is done, I'll get it everytime.) My try statement has to say something to the effect that if the user trys to enter a non-integer value....am I right so far???
try
//Calling the user-defined methods
multiplier = getNumber();
correct = takeQuiz(multiplier);
System.out.println("\t\tYou got "+correct+ " correct!" );
user inputs any invalid, non-integer
catch (NumberFormatException e)
}

Why is there a java enable function in the settings app if java ia not supported by ipad2?

Why is there a java enable function in the settings app of the ipad2, ios5, when java is not supported by ios5 on the ipad2? The adds say that java neo, I think that is what it is supposed to be called, was supposedly introduced into the ios5 format to deal with this?

If you're looking in the settings for Safari, that's JavaScript, which despite the similarity in names is completely different from Java. Java is not, never has been, and all indications are never will be supported in iOS. I have no idea what "java neo" might be, but I've never seen Java mentioned in any way in any of Apple's iPad ads.

Java Jobs

I learning java and I just want to know what java jobs are in demand, what type of java programming would most likely get me a job.

You may still be able to pick up a bit of legacyJava
work here and there, but these days, without .NET
you're gonna struggle.I find this very hard to believe....legacy java? I
don't think so.I agree that it is hard to believe, even Apple have a new native API that java programmers can plug into, as it has seen Java is in so much demand and would like people to use their computers, or at least program for them. The name of this is Cocoa, and no I am not an Apple buff :)

Error in Report Output

Hi Every one,
I have an issue in one Oracle report developed in 10g. I am able to get pdf output in User Interface but not Excel output. so I have gone through other oracle report existing which have EXCEL output in UI. I have seen JAVA code as 'desformat=spreadsheet<code>desformat=xls'
when I put the same code for my report, it is rendering the following ERROR:
Error
REP-1814: Report cannot be formatted. Object 'horizontally' can never fit within 'B_1'.
can anybody please let me know the solution for this. this is Urgent.
Thanks in Advance.

Hi,
You can get output in PDF as you see in report runtime preivew.
But you can't get same output in .txt.
Bcoz if it is in .txt , there is a problem with null strings for each of the columns..
Bcoz the report is in bit-map mode.
So plz change it into Character mode.
go thru steps mentioned in reports--help.
type character mode settings.
try with this.

JVM crash on Debian Linux

Hi
I am running some simple web applications in Tomcat on a Debian Linux machine and my JVM is crashing frequently. The server load is very low.
Mostly it is the java.net.Inet4AddressImpl.getHostByAddr(Native Method) that causes the crash but i have also seen java.lang.Thread.start(Native Method) crash. The library /lib/tls/libc.so.6 is always involved.
Configuration:
J2SE v 1.4.2_07-b05 SDK
GNU/Linux 2.6.11.2 Debian Sarge
Tomcat 5.0.30
I would be very thankful if someone could help me out with this!
Here is the error log:
An unexpected exception has been detected in native code outside the VM.
Unexpected Signal : 11 occurred at PC=0xB7F25604

Hi
Does a simple java.net.InetAddress.getHostName fail?
How about not using NPTL? Not too familiar with linux but since u mentioned tls is always seen when using tls.
Hope this helps.

Multi monitor problem

hi everybody!
i have the desktop expanded on 2 monitors. and now, if i play a game i can motion the mouse on the second monitor. so if i press a mouse button, the game minimized.
do you know what i mean and can help me?

From what I've seen, Java can't programmatically make a single window span multiple monitors. One JFrame (or one JWindow, or one fullscreen window) per monitor seems to be the only way to go. There doesn't seem to be a problem with this approach; you'd just have to shift pages from one frame to the other (presumably you could just move whatever object you're displaying in the page, rather than re-parsing the HTML.)

AFAB program performance different if TEST switch activated

Hi colleagues,
We are experiencing a strange performance in AFAB program.
We have uploaded several assets in a particular company code. When executing AFAB transaction in TEST mode, the new assets are not considered, whereas, when performing a REAL execution yes they are.
We think that when reconciliating assets at the end of the year, this issue which is not harmful (but strange indeed) may be solved, but we are not sure at all.
Can anybody provide a clue on what is happening.
Thanks and my best regards

JNI and Out of Memory errors

Hi,
At my job, we seem to have a memory leak related to JNI. We know we
have a memory leak because we keep getting Out of Memory errors even
after increasing the maximum heap size to more than 256 megs. And we
know that this is the application that is eating up all the system
memory.
We are running under Windows 2000, with both JDK 1.3.0 and JDK 1.4.1.
We tried looking at the problem under JProbe, but it shows a stable
Java heap (no problems, except that the Windows task manager shows it
growing and growing...)
I tried a strip down version, where I set the max heap size to 1 Meg,
and print out the total memory, memory used, and maximum memory used at
a 5 sec interval.
Memory used = Runtime.getRuntime().totalMemory() - Runtime.getRuntime().freeMemory().
Well, I let that strip down version running for about a day. The
maximum memory used has stabilized to about 1.1 Meg, and has not
increased. The current memory used increases until it gets to some
threshold, then it decreases again. However, the Windows task manager
shows the memory increasing -- and currently it is at 245 Megs!
In the lab, the behavior we see with the Windows task manager is as
follows:
1. Total memory used in the system increases until some threshold.
2. Then it goes back down by about 100 Megs.
3. This cycle continues, but at each cycle the memory goes back down
less and less, until the app crashes.
Now, our theory is that JNI is consuming all this memory (maybe we are
using JNI wrong). That's the only explanation we can come up with to
explain what we have seen (Java showing an OK heap, but the task
manager showing it growing, until crashing).
Does that make sense? Can the new operator throw an Out of Memory
error if the system does not have enough memory to give it, even if
there is still free heap space as far as the Runtime object is
concerned? Does the Runtime object figures objects allocated through
JNI methods into the heap used space?
Note that I know the task manager is not a reliable indicator.
However, I don't think a Java app is supposed to runaway with system
memory -- the problem is not simply that the Java app is consuming too
much memory, but that it seems to always want more memory. Besides, we
do get the Out of Memory error.
Thanks for your help,
Nicolas Rivera

Hi,
there are two sources of memory leakage in JNI:
- regular leaks in c/c++ code;
- not released local/global references of java objects in JNI.
I think that the first issue in not a problem for you. The second is more complex. In your JNI code you should check
- how many local references alive you keep in your code as their number is restricted (about 16 and can be enlarged). The good style is not to store local references but keep only global.
- any local reference accepted from java call in JNI are released by JVM. You should release local references you created in JNI and also global references.
- do not use a large number of java object references. Each new reference gets new memory in JVM. Try to reuse refences.
I guess that is your problem.

Read TIF image properties

How can I read all the properties of TIFF like "SUMMARY", "TITLE" , "AUTHOR" etc.... which are actually seen when you RIGHT CLICK on the image?????
Also some of the images have additional custom tab named "imagedetails" which should also be read programmatically.
This custom tab is not normally displayed on right click. It is displayed when I install "eistream" imaging s/w.
I have seen java imaging api's but could not find which tag could read the right click properties of TIFF image.
Please suggest the right API for obtaining the right click properties of TIFF image file.

I am still getting problems here, but I don't know that my imagereader is correct.
public class Test {
     public static void main(String[] args) {
          File in = new File("te.tif");
          ImageReader reader = (ImageReader)ImageIO.getImageReadersByFormatName("tif").next();
          System.out.println("Found reader " + reader);
          ImageInputStream iis = new FileImageInputStream(in);
          reader.setInput(iis);
          System.out.println(in + " contains " + reader.getNumImages(true) + "pages");
          IIOImage iimage = reader.readAll(0, new ImageReadParam());
          IIOMetadata imageMetadata = reader.getImageMetadata(0);
          //Get the IFD (Image File Directory) which is the root of all the tags
          //for this image. From here we can get all the tags in the image.
          TIFFDirectory ifd = TIFFDirectory.createFromMetadata(imageMetadata);
          TIFFField allFields = ifd.getTIFFField();
          for (int i = 0; i < allFields.length; i++) {
               TIFFField field = allFields;
               String name = field.getTag().getName();
               int number = field.getTagNumber();
               String type = TIFFField.getTypeName(field.getType());
               String value = field.getValueAsString(0);
               System.out.println("- " + name + ", " + number + ", " + type + ", " + value);

Content-Type=application/x-www-form-urlencoded with UTF-8 data which servlet fails to interpret correctly .

My Environment is Weblogic 6.1 SP2 on WIN2K.
I have an HTTP client sending an HTTP request with
Content-Type=application/x-www-form-urlencoded
the data in HTTP request is in UTF-8. Note that HTTP client does not specify charset=UTF-8
as part of the Content-Type.
I have a servlet "VosXmlEvents" processing this HTTP request.
The HTTP request contains data like “Zoë” which the servlet below
interprets as “ZoÃ«” causing me to think that my deployment settings
might be wrong.
My Deployment settings:
In weblogic.xml deployment descriptor I have specified following:
<charset-params>

<input-charset>
<resource-path>/vos/events/xml/*</resource-path>

<java-charset-name>UTF8</java-charset-name>
</input-charset>

<charset-mapping>
<iana-charset-name>ISO_8859-1:1987</iana-charset-name>
<java-charset-name>ISO-8859-1</java-charset-name>
</charset-mapping>
<charset-mapping>
<iana-charset-name>ISO_8859-1:1987</iana-charset-name>
<java-charset-name>ISO8859_1</java-charset-name>
</charset-mapping>
<charset-mapping>
<iana-charset-name>UTF-8</iana-charset-name>
<java-charset-name>UTF-8</java-charset-name>
</charset-mapping>
<charset-mapping>
<iana-charset-name>UTF-8</iana-charset-name>
<java-charset-name>UTF8</java-charset-name>
</charset-mapping>
</charset-params>
My web.xml has:
<servlet>
<servlet-name>VosXmlEvents</servlet-name>
<servlet-class>some class name</servlet-class>
</servlet>
<servlet-mapping>
<servlet-name>VosXmlEvents</servlet-name>
<url-pattern>/vos/events/xml/*</url-pattern>
</servlet-mapping>
According to Servlet spec. 2.3 sec. SRV.4.9 Request data encoding, cut pasting
from spec below:
"Currently, many browsers do not send a char encoding qualifier with the Content-Type
header, leaving open the determination of the character encoding for reading HTTP
requests. The default encoding of a request the container uses to create the request
reader and parse POST data must be “ISO-8859-1”, if none has been
specified by the client request. However, in order to indicate to the developer
in this case the failure of the client to send a character encoding, the container
returns null from the getCharacterEncoding method.
If the client hasn’t set character encoding and the request data is encoded
with a different encoding than the default as described above, breakage can occur.
To remedy this situation, a new method setCharacterEncoding(String enc) has been
added to the ServletRequest interface. Developers can override the
character encoding supplied by the container by calling this method. It must be
called prior to parsing any post data or reading any input from the request. Calling
this method once data has been read will not affect the encoding."
Q1. Should not <input-charset> related settings in weblogic.xml for a servlet
helps container actually do some thing like setCharacterEncoding(String enc) on
HTTP Request before it call the servlet?
Q2. If not then that would mean I have to programatically call setCharacterEncoding(String
enc)to correctly interpret my HTTP Request?
Q3. If the answer to Q1 is "yes" then I will assume that getInputStream() or getReader()
methods on the HttpServletRequest will give the chacter in the client encoded
format which in this case is UTF-8, i.e I will get "Zoë" as in this example. Am
I correct here?

1. http://edocs.bea.com/wls/docs70/webapp/components.html#139932
2. http://java.sun.com/j2se/1.3/docs/guide/intl/encoding.doc.html

Stefan,
Thanks for the information. I have the following question then.
The Webserver I am interacting with does not recognize user and password provided in the channel. It accepts user and pwd in payload and in application/x-www-form-urlencoded content type only.
Sample Raw Post that server server requires looks like this
User=yourname&Password=yourpassword&INPUT_XML=%3C%3Fxmlversion%3D%221.0%22standalone%3D%22no%22%3F%3E%3CDELIVERY%3E%3CMESSAGE%3E%0D%0A++++%3CDESTINATION_ADDR%3E%2B447900570205%3C%2FDESTINATION_ADDR%3E%%3C%2FMESSAGE%3E%0D%0A%0D%0A%3C%2FDELIVERY%3E%
What i have done is that constructed the post manually in Java code in un encoded form and expected the HTTP Adapter to do the encoding. Having done this, the HTTP Server is able to scuccessfully parse the xml except for & and < , > chars which err out as invalid XML.
Is there an elegant way of doing above scenario using XML post and standard HTTP Adapter.
Best Regards,
Sudharshan N A

How to handle modules in OOP

Hi,
I am writing a simple Rock-Paper-Scissors program and I read a lot of basic stuff so far, also read some parts of Code Complete, but I still have some basic questions about the structure of an OOP program:
- If I have "module" of the program (for example that calculates the computer's choice in my Rock-Paper program based on my previous choices) that is too big to put it into a method, do I have to create a class for it? For what I read so far, classes are not to pack some part of the code together, but I don't how else could I handle a module of a program. In my Rock-.. program I would call it Calculator, I think it's ok, for example I've seen java.util.Scanner, which is some kind of "doer" packed in a class, too.
- But if I create this class, it would not be a blueprint for objects. I only need one object, so should I use that so called singleton pattern?
- Or should I make every field in this object static instead of the singleton pattern?
(I also don't know what the Main class and main() method should usually contain, I don't know if this connects to this in any way, so this might be another topic..)
Thanks in advance for any help.

I'm not 100% sure if you are using the right terminology. I normally think of a module as a grouping of functionality, in Java normally a series of classes (more likely a group of packages).
Generally, if logic is too complex, you need to break it into smaller, discrete pieces. Ideally, each method does one thing and only one thing well. This has nothing per se to do with OOP. You could do the same procedurally with namespaces (or packages or whatever they offer) and organizing your source files.
Within Java, you would have the option of breaking your larger method into smaller (likely private) methods. Then once you see that different methods have different responsibilities, you may refactor your design into separate classes.
- But if I create this class, it would not be a blueprint for objects. I only need one object, so should I use that so called singleton pattern?Are you talking classes or objects? Your design may need one or more classes. A singleton is a pattern that when implemented ensures at runtime that only one instance (object) of a class exists in a given JVM.
- Or should I make every field in this object static instead of the singleton pattern?
I think you are conflating things here. What is motivating you to make something static?
(I also don't know what the Main class and main() method should usually contain, I don't know if this connects to this in any way, so this might be another topic..)
Yes, another topic. The class can be named anything. It simply needs a main() method with a valid signature to act as an application entry point.
Thanks in advance for any help.You are welcome.

Business logic in PL/SQL?

Hello,
I am designing a 3-tier, web-based intranet application for my client. It's going to be a WebSphere portal app with Struts, running on Oracle 8.1.7.
One of the requirements is to implement the business logic in the back-end (PL/SQL), not in Java (although that is what I'm used to do). The reason probably has something to do with fear of performance issues ("the more code runs in Oracle, the faster") and resource planning ("more people here know Oracle better than Java").
This unusual (?) choice in my humble opinion leaves me with two major issues; how to cache database results and how to perform the O/R mapping.
I know how to use CallableStatements and JDBC, but I'd really like to avoid such a solution now we have EJB 2.1 and Hibernate and everything. And without caching as done by any sensible app server I fear performance issues.
Does anyone know a tool that can perhaps generate Java code and performs the O/R mapping? Or a tool that avoids me having to implement up to a hundred (!) CallableStatements and ResultSet-To-JavaBean mappings. I've seen Apache's commons-dbutils that seems to do this.
Does anyone have experience implementing business logic in PL/SQL and calling procedures from Java? Is performance really an issue here?
Thanks in advance for any input,
regards,
Bram Rooijmans

This unusual (?) choice in my humble opinion leaves me
with two major issues; In non-trivial applications excluding all business logic from the database is usually an architecture or design bug. Businesses do use the database directly due to legacy, tools, comfort level, etc. And in those cases the data still needs to be consistent. Not to mention that for some business logic the database can be orders of magnitude faster in running it versus external logic.
On the other hand I would consider it a bug as well if someone told me that all the business logic must be in the database and no where else. (At the very least I would suspect and question their definition of business logic in that case.)
I know how to use CallableStatements and JDBC, but I'd really like to avoid such a solution now...How are you going to implement any non-trivial business logic in oracle without using stored procs?
Does anyone have experience implementing business logic in PL/SQL and
calling procedures from Java? Not sure of the question. Certainly I have implemented business logic in PL/SQL. And many people have used stored procs via java.
Is performance really an issue here?No idea. That is a dependency of your system, not of java/databases in general.
I have seen java only solutions that even with scalling take hours to do operations that could be done in much less time using the database itself.
I have seen requirements which would have taken hours even in the database and changing the requirements meant it took less than 2 minutes. (It had nothing to do with java nor the database.)
I have seen code implementations which took significant database processing time where the entire solution could have been done without the database at all.
I have seen solutions where, due to business requirements, the same business logic was implemented in different languages and in slightly different ways in each. Implementing the logic in stored procs meant that all of the systems that used it now would be using the same rules. In that case it is possible that the solution was actually slower. But if it was it was not noticed and the consistency was much more important.

Hard code of IP Address

hi
I have seen java code Containing IP Address of Other server. But when we have most java (components)files containing IP Address in the code, to make a hit to another Server, then it becomes tedious process to change these IP Address in all the file(components) when necessary. So is there any way to generate java file which will take care of these...
like Hash table where it fetch the IP Addresses....
Please some one Elucidate on this issue.

Why not just put the IP address(es) in a configuration file? It's pretty easy to read and write simple properties using the java.util.Properties class.

I seen Java ?
